Following up on our “they really will be everywhere” theme, Laurie Sullivan of RFID Journal reports that sensor networks do not even need direct solar energy to operate now:
Forest-Monitoring Sensors Harvest Energy From Trees
The U.S. Forest Service is deploying a climate sensor network powered by energy harvested from living trees
July 2, 2009—The U.S. Forest Service has confirmed that it will purchase a climate sensor network this summer from Voltree Power that is powered by energy harvested from living trees. The system employs low-power radio transceivers, sensors and patented bioenergy-harvesting technology to predict and detect fires.
Using the word ‘parasitic’ here is more an attempt at humor than a complaint; the bioenergy-harvesting is a very clever technical achievement. Our point here is that soon there won’t be anywhere that sensors can’t operate… —Chris Peterson
